I’m pretty sure that I’ve posted a tutorial for envelope liners previously but they’re fun to do and an easy way to spiff up an announcement so here is another quick little tutorial.
Envelope (these are size A7)
Thin, non-ribbed cardboard (I used a GAP gift box top) (must be bigger than envelope)
Double sided tap
Decorative paper (not shown), used for the liner
Nice to have: A cutting mat
Start by tracing the outline of the envelope onto the cardboard
Cut out the envelope shape:
Snip off a few inches from the bottom. I will also trim a bit from the sides so it easily slides into the envelope.
You want to make sure that the cardboard doesn’t interfere with the glue strip on the envelope. This is perfect:
Using your new cardboard template, lay it onto your liner paper (which should be face up), and cut around it with the knife.
Slip the liner into the envelope to make sure it’s a good fit:
With the liner still inserted, bend it backwards (but don’t crease) and then use the tape gun to lay down a line of tape that mimics the glue line
That’s the glue line of the envelope along the outside and my tape line immediately below. This is the only place the liner is attached to the envelope.
Lay your liner down against the tape (give it a good rub to make sure it’s attached) and then fold the envelope flap down to create the crease.
This is what it looks like when you re-open the envelope:
Insert your card, put a little spit on that glue line, and ta da! finished.
PS: Here are a few more pictures of the finished product, along with sources of the cards, envelopes, and paper.
